Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Considering they both belong to the city car segment and utilize the same 5-door hatchback body style and the front wheel drive system, it all comes up to the specific petrol engine choice they offer. The first one has a Hyundai-engineered powertrain under the hood, a 4-cylinder, 16-valves 109hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 100hp engine designed by Opel.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the same number of safety stars gained in the process. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the city car segment, which is generally not a very good thing safety-wise, but it doesn't do much to help us decide between the two. On the other hand, taking kerb weight as an important factor into account, the American car offers a marginal difference of 2% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Chevrolet does have a slight advantage, when all the models are taken into account. That's the official data, while our visitors describe reliability of KIA with an average rating of 4.6, and models under the Chevrolet badge with 4.2 out of 5. The same official information place Rio as average reliability-wise, and Aveo is more or less at the same level.Above it all, drivers of cars with the same engine as the Korean car rank it on average as 4.5 out of 5, exactly the same as the other one.

KIA is a bit more agile, reaching 100km/h in 0.7 seconds less than its competitor. In addition to that it accelerates all the way to 183 kilometers per hour, 6km/h more than the other car. When it comes to fuel economy the winner has to be the Korean car, averaging around 5.1 liters of fuel per 100 kilometers (55 mpg), in combined cycle. We can't ignore that 16% difference compared to the American car.

Chevrolet appears just a bit more reliable, although the difference is truly marginal. The most important thing when deciding between any two vehicles should always be safety, both passive and active. In my opinion, everything taken into account, the American car offers slightly better overall protection and takes the lead. From there things take a different direction, with KIA offering somewhat better performance, just enough to call it quicker. To make things even better, it consumps less fuel! I believe that, when we take all into account, we have only one winner here - the KIA. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel. I'm only here to help. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser™, out of 12.000+ vehicles we currently have in our database.
